Abstract:

Background: Orange juice and Carbonat drink contains an acid agent which can affect the surface hardness of composite resin. Changes of surface hardness of composite resin is caused by infiltration of water containing the acid agent that affect the bonding of matrix to filler composite resin. This study purpose to determine the effect of immersed orange juice and carbonat drink on surface hardness of composite resin. Method: This was experimental laboratory study with a pre and post test control group design. The samples of composite resin had 12 mm in diameters and 2 mm in thickness (n=27). Composite resin used is FiltexTM Z350 XT shades A2. Samples were divided into three groups : group A immersed with orange juice, group B immersed with carbonat drink, and group C immersed with aquadest as the negative control. Samples were immersed for 24 hours. The pre and post immertion of composite resin surface hardness were measured with Micro Vickers Hardness Tester. Results: Post immertion Vickers hardness was compared by using one way anova test. The result showed that immersed orange juice and carbonat drink significantly reduced the surface hardness of composite resin (p < 0,05). Concluision: The conclusion Immersed carbonat drink more reduced the surface hardness of composite than orange juice. It is suggested to reduce the duration direct exprossure of consumption carbonat drink.

Abstract:

Mixed lactic acid bacteria culture is commonly used in yogurt production. In the present study, two lactic acid bacteria (Lactobacillus bulgaricus and Streptococcus thermophillus) was used as starter culture. Calcium carbonate was added to the starter culture to increase the quality of mixed starter culture of L. bulgaricus and S. thermophillus with ratio of 4:1. The present study was directed to investigate the chemical composition of mixed starter culture with and without calcium carbonat addition. Furthermore, the effect of each starter culture on yogurt product chemical composition was also examined. The pH, lactose, soluble protein and acid content was determined as chemical composition parameters. For starter culture without calcium carbonate addition, the yogurt has pH, lactose, soluble protein and acid content of 4.18–4.39, 4.18–4.39% w/v, 2.88–4.36% w/v and 0.82–0.99% w/v, respectively. While for starter culture with calcium carbonate addition, the yogurt product has pH, lactose, soluble protein and acid content of 4.26–4.37, 1.47–1.75% b/v, 3.42–4.95% w/v and 0.86–1.11% w/v, respectively. Addition of 0.05% w/v calcium carbonate to mixed starter culture gave effect on lactose consumption, where it still can convert lactose to lactic acid up to 45 days of storage. Furthermore, the yogurt product made with starter culture with calcium carbonate addition has higher soluble protein content compared to yogurt made with starter culture without calcium carbonate addition

Abstract:

In the article, the temperature dependence of the viscosity of a complex inorganic substance - potassium carbonate was obtained and the proposed mathematical model was verified. Viscosity is considered as a chaosensitive property of a liquid inherent in it in motion and at rest. The mathematical model of viscosity was developed using the Boltzmann distribution and the concept of chaotic particles. On this basis, a hierarchical cluster-associate viscosity model is constructed, which takes into account not only the formation of primary clusters, but also secondary associates with respect to them, with the possibility of identifying the degree of cluster association. To adapt the cluster-associated model to experimental data, certain data processing techniques have been developed to identify unknown parameters of the model. The method of processing viscosity data using the entire set of three reference points allows you to determine the indicator of the degree of aggregation of associates. When processing the data on the viscosity of potassium carbonate, a high correlation coefficient was established calculated in comparison with reference values, which indicates the adequacy of the new relationship. This model makes it possible to predict the behavior of the viscosity of potassium carbonate in a higher temperature range. The degree of association of clusters with an increase in temperature decreases, corresponding to the dynamics of the destruction of associates and viscosity in general.

Abstract:

The research area is a part of South Serayu Mountain zone, specifically Bregada Kulon Progo. The Bregada Kulon Progo is a product of volcanic activity in the past, which can be seen by the volcanic rock called Old Andesite Formation. The end of the volcanic activity is characterized by the deposition of carbonate rocks which were part of Jonggrangan Formation and Sentolo Formation. The lower part of Sentolo Formation is composed by the mix of carbonate and volcanic materials. The research is carried out by two methods. The first is field method, which is implemented by geological mapping and rock sampling. The second is laboratory method, which is implemented by petrographic method. The petrographic method is implemented by making thin section of the rocks, then observing the thin section with polarization microscope to determine the composition of the rocks. The rock samples are mainly from the lower and middle part of Sentolo Formation, which probably still got the influence of volcanic activity. The benefit of the research is knowing the influence of volcanic activity in the carbonate rocks of Sentolo Formation. The presence of volcanic materials in the lower part of Sentolo Formation, can be predicted by two processes. First, the volcanic activity supplied those materials directly, and second, from the rework of the volcanic materials then mixed with carbonat materials of Sentolo Formation.

Abstract:

El desenvolupament de substitucions propargíliques catalitzades per metalls de transició o reaccions de tipus SN2 de carbonats cíclics propargílics i altres heterocicles relacionats proporcionen estratègies eficients per construir molècules i materials orgànics complexos. L’ús del coure és molt conegut per transformacions catalítiques de substitució propargílica asimètrica de carbonats cíclics substituïts amb alquins terminals a través d’intermedis de tipus Cu-al·lenilidè. Tot i així, les reaccions de tipus SN2 catalitzades per coure de carbonats cíclics substituïts amb alquins interns o heterocicles similars no han sigut explorades. Basant-nos en resultats recents del nostre grup, hem dissenyat una funcionalització descarboxilativa catalitzada per coure de carbonats cíclics substituïts amb alquins interns incorporats amb reactius de diboro(4) o sililborans. Aquesta nova transformació proporciona nous paradigmes de reactivitat oferint una gamma més àmplia de compostos útils sintèticament i, a la vegada, aporta informació addicional sobre el mode de funcionament del catalitzador. Un altre dels protocols amb un objectiu atractiu desenvolupats en aquesta tesis és la preparació de productes enantioenriquits mitjançant reaccions estereoespecífiques catalitzades per níquel. Tenint en compte que els compostos d’organosilici i d’organobor es caracteritzen per l'estabilitat, baixa toxicitat i la facilitat d’ús, creiem que el desenvolupament d'aquests compostos contribueix a ampliar la caixa d'eines sintètiques de la química orgànica oferint noves oportunitats de síntesis per a la química fina.<br>El desarrollo de sustituciones propargílicas catalizadas por metales de transición o reacciones de tipo SN2 de carbonatos cíclicos propargílicos y otros heterociclos relacionados proporcionan estrategias eficaces para construir moléculas y materiales orgánicos complejos. El uso de cobre es muy conocido para transformaciones catalíticas de sustitución propargílica asimétrica de carbonatos cíclicos sustituidos con alquinos terminales a través de intermedios de tipo Cu-alenilideno. Aun así, las reacciones de tipo SN2 catalizadas por cobre de carbonatos cíclicos sustituidos con alquinos internos o heterociclos similares son inexploradas. Basándonos en resultados recientes de nuestro grupo, hemos diseñado una funcionalización descarboxilativa catalizada por cobre de carbonatos cíclicos incorporados con alquinos internos con reactivos de sililboro o diboro(4). Esta nueva transformación proporciona nuevos paradigmas de reactividad ampliando la gama de compuestos sintéticamente útiles y, al mismo tiempo, brinda información adicional sobre el modo de funcionamiento del catalizador. Otro de los nuevos protocolos con un objetivo atractivo desarrollados en esta tesis es la preparación de productos enantioenriquecidos a través de reacciones estereoespecíficas catalizadas por níquel. Teniendo en cuenta que los compuestos de organosilicio y de organoboro se caracterizan por su estabilidad, baja toxicidad y fácil manejo, creemos que el diseño de estos compuestos contribuyen a ampliar las herramientas sintéticas de la química orgánica ofreciendo nuevas oportunidades de síntesis para la química fina.<br>The development of TM-catalyzed propargylic substitution or SN2'-type reactions of propargylic cyclic carbonates and related heterocycles has provided an efficient strategy to construct complex organic molecules and materials. Even though Cu catalysis has been shown to be very successful in promoting the asymmetric propargylic substitution of terminal alkyne-substituted cyclic carbonates via Cu−allenylidene intermediates, Cu-catalyzed SN2'-type reactions of internal alkyne-substituted cyclic carbonates or similar heterocycles remains unexplored. Based on previous reports and recent achievements in our group, we envisioned that the development of Cu-promoted decarboxylative functionalization of (internal) alkyne-substituted cyclic carbonates with silylboron or diboron(4) reagents would potentially provide new reactivity paradigms while giving additional insights into the operating mode of the catalyst and delivering a more ample range of synthetically useful compounds. In addition, new catalytic protocols that can foster the easy preparation of enantioenriched products via stereospecific Ni-catalyzed reactions would also be an attractive target. Considering that organosilicon and organoboron compounds are characterized by stability, nontoxicity, and easy handling, the development of these compounds is believed to contribute to amplify the synthetic toolbox of organic chemists offering new synthetic opportunities for a wide range of fine-chemical targets.

Abstract:

La tesi se centra en l'activitat dels aminotrifenolatos d'alumini en l'activació de epòxids i la seva posterior acoblament a altres molècules en la formació de diferents heterocicles. El catalitzador és un àcid de Lewis que en interaccionar amb el epòxid augmenta la electrofilia d'aquest, afavorint processos d'obertura de cicle i acoblament a heterocumulenos com el CO2 o el SO2. Hem aconseguit descriure metodologies per a la síntesi de oxazolidinones, carbamats, sulfits cíclics o carbonats cíclics. Molts d'aquests processos ja havien estat descrits amb anterioritat per epòxids terminals, per això nosaltres ens hem centrat en epòxids cíclics la reactivitat és menor ia més els seus productes són més interessants en ser més similars a productes naturals. Estudiant els diferents mecanismes relacionats amb aquestes reaccions i variant les condicions i components dels nostres sistemes catalítics hem aconseguit que totes les nostres síntesi siguin estereoselectives i en algun cas fins i tot estereodivergente.<br>La tesis se centra en la actividad de los aminotrifenolatos de aluminio en la activación de epoxidos y su posterior acoplamiento a otras moleculas en la formación de distintos heterociclos.

We describe methodologies for the synthesis of oxazolidinones, carbamates, cyclic sulfites or cyclic carbonates. Many of these processes had already been described for other catalyst systems, but we have focused on the less reactive cyclic epoxides, whose products are more interesting as they have similarities to many natural products. Studying the different reaction mechanisms related to these reactions and changing the components and conditions of our catalytic system we have achieved complete stereoselectivity in our reactions and even in some cases stereodivergence.

Abstract:

Les reïnes epoxi estan dins dels polímers més utilitzats com a materials per aplicacions elèctriques i electròniques. Se les pot trobar com a aïllants en materials conductors i en la construcció de turbines i commutadors degut a la bona combinació de propietats tèrmiques, elèctriques i mecàniques que posseeixen. A més, tenen un cost relativament baix i són fàcils d'aplicar. Un dels seus majors usos és el de recobriments en microelectrònica. La protecció dels delicats xips contra agents atmosfèrics, pols, humitat i desgast mecànic s'ha de realitzar amb un material que sigui capaç de polimeritzar sense produir una gran contracció i amb un coeficient d'expansió tèrmica similar al dels components del xip.<br/>Degut a aquests requeriments l'ús de les reïnes epoxi es veu sovint limitat per una sèrie d'inconvenients que presenten com són la seva persistència en el medi ambient una vegada finalitzada la seva útil, la fragilitat dels materials que s'obtenen i la contracció que sofreixen durant el curat. Per tal de solucionar aquests problemes, en la present tesi s'ha estudiat la copolimerització de la reïna epoxi de diglicidiléter de bisfenol A (DGEBA) amb monòmers expandibles, com són els espiroortocarbonats (SOCs) i els carbonats cíclics de cinc i sis membres. A més, s'ha optat per la polimerització per obertura d'anell ja que és el mecanisme que comporta una menor contracció. <br/>Els espiroortocarbonats són considerats monòmers expandibles degut a que durant la polimerització és produeix un canvi de distàncies d'enllaç del monòmer al polímer. Per cada enllaç covalent que es forma al polimeritzar se'n trenquen dos en el monòmer, que passen a distàncies de Van der Waals, contrarestant la contracció. En els carbonats cíclics l'expansió és deguda al canvi de interaccions que experimenten al polimeritzar passant d'una forta interacció entre monòmers a una interacció més feble entre cadenes polimèriques. <br/>La copolimerització s'ha realitzat tant catiònica com aniònicament. Per la copolimerització catiònica s'han utilitzat diferents triflats de lantànid, preferentment el de lantà i el d'iterbi ja que aquest són els que presenten més diferències quan a l'acidesa de Lewis i a la duresa de Pearson. Aquests iniciadors no són convencionals per polimeritzacions catiòniques però han demostrat tenir la capacitat de dur a materials entrecreuats amb bones propietats mecàniques i menys fràgils que els obtinguts utilitzant com a iniciador els complexos de BF3 que s'utilitzen habitualment per a polimeritzacions catiòniques. Per la copolimerització aniònica s'ha utilitzat com a iniciador la N,N-dimetilaminopiridina (DMAP). <br/>La copolimerització del DGEBA amb SOCs o amb carbonats cíclics permet introduir grups carbonat a la xarxa. Aquests grups són tèrmicament escindibles amb el que s'han obtingut materials tèrmicament degradables a temperatures moderades. A més, la introducció d'una part alifàtica, procedent dels monòmers expandibles, així com l'augment en la distància entre nusos ha permès obtenir materials menys fràgils ja que la xarxa té més mobilitat. També s'ha aconseguit reduir la contracció després de la gelificació respecte a la que experimenta en curar la reïna pura i en la copolimerització amb l'espiroortocarbonat s'ha aconseguit reduir la contracció global, arribant a materials amb una contracció inexistent i en una de les mostres s'ha obtingut un material que inclòs s'havia expandit.<br>Epoxy resins are among the most important thermosetting materials used as electric and electronic packaging applications. They are used like insulators in conductive materials and in construction of turbines and commutators due to good mechanical, electrical and thermal properties. In addition, they have a low cost and they are easy to apply. One of their more important uses is as coatings, underfills and encapsulants in microelectronics. The protection of delicate chips against atmospheric agents, dust, humidity and mechanical erosion must be done with a material able to cure without producing a great contraction and with a coefficient of thermal expansion similar to the ones of the components of the chip.<br/>Due to these requirements sometimes the epoxy resins have limited their use due to a series of disadvantages that display as their persistence once their utility life is over, their fragility and the contraction that experiments during curing. With the aim to solve these problems the diglycidyl ether of bisphenol A (DGEBA) has been copolymerized with expanding monomers such as spiroorthocarbonates (SOCs) and five and six membered cyclic carbonates. In addition, we choose the ring-opening polymerization mechanism because it leads to a smaller contraction.<br/>Spiroorthocarbonates are considered expandable monomers because there are changes in the linking distances in the monomer, when it transforms into the polymer. By each covalent linkage that forms on polymerizing, two covalent linkages transform into Van der Waals distances, reducing the contraction. In the cyclic carbonates the expansion is due to the change of interactions that experiments on polymerizing, which transform a strong interactions between monomers to a weaker interaction between polymeric chains. <br/>The copolymerization has been done with cationic and anionic initiators. In the cationic polymerization we used different lanthanide triflates, mainly ytterbium and lanthanum triflates because they have the higher differences in their Lewis acidity and their Pearson hardness. These initiators, which are not conventional, proved to be able to conduct to thermosets with good mechanical properties and less fragile. In anionic polymerization we used N,N-dimethylaminopyridine (DMAP) as initiator. <br/>The copolymerization of DGEBA with SOCs or cyclic carbonates allow incorporate carbonate groups in the network. These groups are thermally cleavable and therefore we could obtain materials, which can be degraded at moderate temperature. Furthermore, the presence of aliphatic moieties, which comes from expandable monomers, and the increase in the length between crosslinks allowed the preparation of less fragile materials, because the higher mobility of the network. Moreover, we could reduce the contraction after gelation in comparison to that experimented by the curing of the pure resin. In addition, in the copolymerization with the spiroorthocarbonate, we can reduce the global contraction obtaining materials with zero shrinkage and in one of the samples we obtained even an expansion in the material.

Abstract:

La present Tesi doctoral s'inscriu en el marc del conveni de col·laboració per a la seva co-tutela suscrit entre la Universitat Rovira i Virgili, i la Université Abdelmalek Essaadi de Tetuán (Marroc) i que s'inicià en el marc dels projectes d'investigació conjunts hispano-marroquís de referèncias A/015931/08 i C/030686/10 del Programa de Cooperación Interuniversitaria e Investigación Científica entre España y Países del Mediterráneo, centrats en estudis catalítics de complexos de coordinació. A la present memòria s'ha realitzat una contribució a la química de coordinació i de derivats de Crom i Manganès a catàlisi homogènia, abordant diferents aspectes de síntesi, caracterizació, reactivitat i propietats catalítiques. L'objectiu de la Tesi és l'obtenció de carbonats orgànics, substàncies amb amplies aplicacions, a partir d'alquens amb la utilizació de diòxid de carboni, un subproducte de la combustió de combustibles fòsils. S'ha plantejat aquest procés en dues etapes. En primer lloc s'ha estudiat l'oxidació dels alquens a epòxids. En una segona etapa, la reacció dels epòxids amb diòxid de carboni dóna lloc a la formació dels carbonats orgànics. Aquestes duess reaccions requereixen la utilizació de catalitzadors. La Tesi s'ha centrat en el desenvolupament d'una família de catalitzadors per a aquestes transformacions basats en complexos de coordinació de metalls de transició amb lligands monoaniònics tridentats NN'O-donadors.<br>La presente Tesis doctoral se inscribe en el marco del convenio de colaboración para su co-tutela suscrito entre la Universidad Rovira i Virgili, y la Universidad Abdelmalek Essaadi de Tetuán (Marruecos) y que se inició al amparo de los proyectos de investigación conjuntos hispano-marroquí de referencias A/015931/08 y C/030686/10 del Programa de Cooperación Interuniversitaria e Investigación Científica entre España y Países del Mediterráneo, centrados en estudios catalíticos de complejos de coordinación. En la presente memoria se ha tratado de realizar una contribución a la química de coordinación y de derivados de Cromo y Manganeso en catálisis homogénea, abordando diferentes aspectos de síntesis, caracterización, reactividad y propiedades catalíticas. El objetivo de la Tesis es la obtención de carbonatos orgánicos, substancias con amplias aplicaciones, a partir de alquenos con la utilización de dióxido de carbono, un subproducto de la combustión de combustibles fósiles. Se ha planteado este proceso en dos etapas. En primer lugar se ha estudiado la oxidación de los alquenos a epóxidos. En una segunda etapa, la reacción de los epóxidos con dióxido de carbono da lugar a la formación de los carbonatos orgánicos. Estas dos reacciones requieren la utilización de catalizadores. La Tesis se ha centrado en el desarrollo de una familia de catalizadores para estas transformaciones basados en complejos de coordinación de metales de transición con ligandos monoaniónicos tridentados NN'O-dadores.<br>This doctoral Thesis has been performed in the framework of a collaborative agreement for the co-supervision of this Thesis, which has been accorded between the Universitat Rovira i Virgili (Tarragona, Spain), and the Université Abdelmalek Essaadi (Tetouan, Morocco). This agreement was initiated with two research projects hispano-moroco with references A/015931/08 y C/030686/10 form the Programa de Cooperación Interuniversitaria e Investigación Científica entre España y Países del Mediterráneo, focused on the catalytic studies of coordination compounds. The objective of the Thesis is to obtain organic carbonates, compounds with wide applications, from alkenes by using carbon dioxide, which is a by product of the combustion of fossil fuels. We have undertaken this process in two steps. In a first step, we studied the oxidation of alkenes to epoxides. In a second step, the reaction of the epoxides with carbon dioxide lead to the organic carbonates. This two reaction require the use of catalysts. The Thesis has focused on the development of a family of catalysts for these two transformations based on transition metal complexes with monoanionic tridentate NN'O-donor ligands.

Abstract:

Separation of some alkaline-earth chlorides (Sr, Ba) was investigated by using carbonate injection method in LiCl-KCl eutectic and LiCl molten salts. The effects of the injected molar ratio of carbonate ([K2 (or Li2)CO3/Sr (or Ba)Cl2]) and the temperature (450–750 °C) on the conversion ratio of the Sr or Ba carbonate were determined. In addition, the form of the Sr and Ba carbonate resulting from the carbonation reaction with carbonates was identified via XRD and SEM-EDS analysis. In these experiments, the carbonate injection method can remove Sr and Ba chlorides effectively over 99% in both LiCl-KCl eutectic and LiCl molten salt conditions. When Sr and Ba were co-presented in the eutectic molten salt, they were carbonated in a form of Ba0.5Sr0.3CO3. And when Sr was present in LiCl molten salt, it was carbonated in the form of SrCO3. Carbonation ratio increased with a decreasing temperature and it was more favorable in the case of a K2CO3 injection than that of Li2CO3. Based on this experiment, it is postulated that carbonate precipitation method has the potential for removing alkali-earth chlorides from LiCl-KCl eutectic and LiCl molten salts.

Abstract:

In this paper, wastepaper gasification with steam and carbon dioxide was tested in the presence of molten carbonate salt catalysts. Reactions with steam or carbon dioxide were first compared. Hydrogen was mainly produced by gasification with steam, but no carbon monoxide was generated. For the case where carbon dioxide was used as a reactant instead of steam, generation of carbon monoxide greatly increased via the Boudouard reaction. Different ratios of mixtures of lithium, sodium and potassium carbonates were examined. Lithium was found to play a critical role in the various catalyst combinations. The reaction rate with respect to carbon conversion was approximately first order for low carbon conversions. The rate constants were investigated at different temperatures (923–1023K) and the activation energies were determined. In addition, the flexibility of this technique was examined with three different types of wastepaper. These results suggest the applicability of this process for the effective use of wastepaper and recovery of carbon dioxide.

Abstract:

Paleozoic platform carbonate rocks of the Rocky Mountains host Mississippi Valley-type (MVT), magnesite, barite, and REE-barite-fluorite deposits. Farther west, platform carbonate rocks of the Kootenay Arc host MVT and fracture-controlled replacement (FCR) deposits. This is the first systematic LA-ICP-MS study of carbonates in MVT and FCR deposits. We investigated seven MVT deposits in the Rocky Mountains, and five MVT deposits in the Kootenay Arc. None of the post-Archean Australian shale (PAAS)-normalized REE profiles show light REE (LREE) depletion and strong negative Ce anomalies characteristic of modern seawater: some profiles are nearly flat; others show depletion in LREE similar to seawater but without negative Ce anomalies; others are middle REE enriched. Carbonates with a strong positive Eu anomaly precipitated from or interacted with different fluids than carbonates with flatter profiles without a strong positive Eu anomaly. REE signatures reflect crystallization conditions of primary carbonates, and crystallization and re-equilibration conditions of carbonates with ambient fluids during diagenesis, deep burial, and/or metamorphic recrystallization. Chemical evolution of fluids along their migration path, fluid-to-rock ratio, fluid acidity, redox, and temperature also influence REE profile shape, which helps establish genetic and timing constraints on studied deposits and improves knowledge of the metallogeny of the Kootenay Arc and Rocky Mountains.
